While some colleges and universities allow you to declare a zoology major at the undergraduate level, you won't be able to find many attractive career opportunities with only a bachelor's degree in the field.

Zoologists are typically trained for several years at a college or university and are involved with a variety of research projects before they can apply for a position in their field.
